Here is potentially an amazing collection of rectifier tubes for tube amps (this range tends to be good in guitar amps) please note i don't have the testing equipment to ensure these work BUT the 40 other tubes i've sold from this lot have been well used and loved! vintage US made tubes, here is whats in this lot:

CBS 5U4GB

Magnavox 5U4G

RCA 5U4G

Motorola 5U4G

GE 5U4GB

Zenith 5Y3GT

GE 5Y3 GT/G

Tung-Sol 5U4 GT

RCA Victor 5V4 G

GE 5V4 G

Zenith 5Y3 GT

again, buyer assumes all risk with these buy i have reason to believe they are good to go based on other sales and on testing the ones i could
